BOILER-FEEDER.

SPECIFICATION formingpart of Letters IlEate11tl\To. 685,280, dated October 29, 1901.

Application filed November 30, 1900. Serial No. 38,088. (No model.)

To alZ whom, it may concern:

Be it known that 1, CHARLES WV. HUNT, a citizen of the United States, residing in \Vest New Brighton, borough of Richmond, city of New York, State of New York, have invented certain new and useful Improvements in Boiler-Feeders, of which the following is a specification, reference being had to the accom panying drawings, forming a part hereof.

This invention relates to boilers of that general type in which a comparatively small volume of water is directly subjected to the action of heat for the generation of steam for power purposes, while provision is made for a sufficient supply of water to keep up the generation of steam for the desired time. Boilers of this class are specially applicable to steam-driven motor-vehicles, and it is with reference to such use that the improved boiler to be described herein has been devised, although it maybe applied to other uses. 7

The invention will be more fully explained hereinafter with reference to the accompanying drawings, in which, for purposes of explanation and illustration, one embodiment of the invention is represented.

In said drawings, Figure 1 is a View, partly in vertical section and partly in elevation, showing somewhat diagrammatically one form of boiler to which the invention is applied. Fig. 2 is a plan view of the boiler shown in Fig. 1.

As represented in the drawings, the steamgenerating portion or compartment or is comparatively small, containing such a volume of water that with a furnace or heater of limited capacity steam will be generated rapidly. A larger volume of water, sufficient to keep up the generation of steam for the desired time, is contained in one or more supply tanks or compartments Z). Each of such compartments or tanks b is connected with the generating-compartment above and below the is not only unnecessary, but in case of accidents the free escape of the water would be highly undesirable. Accordingly, each pipe 0 and d, although uninterrupted,is constricted at a point near the generating-chamber, as at c and d respectively, so that the area of the pipe in cross-section at such point shall be sufficient to permit the normal maximum flow under ordinary conditions of use. This constriction of the supply and return pipes is not only a safeguard in-case of accident, but it retards to some extent the sudden changes of the water-level in the generating-compartment, which are otherwise liable to occur through changes in the position of the vehicle, without preventing the gradual adjustment of level.

For the further purpose of maintaining the water-level in the steam-generating compartment at at or about its normal height regardless of the position of the vehicle to which the boiler may be applied it is desirable to provide a second supply compartment or tank on the opposite side of the generating-compartment,the two supply-compartments being connected together, either directly or through a separate connection of each, with the generating-compartment in any convenient manner. As shown in the drawings, the compartmentb is connected bya pipe 6 with the pipe 0 and by a pipef with the pipe cl. In this manner when, for example, the vehicle is in such a position that the compartment b is the highest the water which flows therefrom will be received partly in the compartment 1) and not altogether-in the generating-compartment 01,, whereby the fluctuation of the water-level in the steam-generating compartment will not be great under any ordinary conditions of use.

It will be understood that the water can be introduced into the boiler at any conven- .ment 6 having been relieved by opening the supply-cock 9' after the cooks c and d are closed. Other cocks h and imay be disposed in the pipes d and f to further control the movement of Water or steam in the boiler, if desired.

The invention is not restricted to the particular construction and arrangement of parts shown in the drawings for purposes of explanation, it being understood that the details of construction and arrangement can be varied Without departing from the spirit of the invention.

I claim as myinvention In a boiler the combination of a steam-generating compartment and water-snpply compartments located on opposite sides of the steam generating compartment and conloss of water by evaporation.

This specification signed and witnessed this 24th day of November, A. D. 1900.
